### Expected Behavior
when uploading a file using the + button in UI, files should be uploaded, or there should be an error message either in UI or in console
### Actual Behavior
Open WebUI quits in console without any error message
### Steps to Reproduce
1. activate py311 environment in Anaconda Prompt
2. run "open-webui serve"
3. open http://localhost:8080/ in Firefox
4. click + button to upload the attached file (it seems that uploading other files larger than a certain size would also trigger the issue)
5. wait until console finishes uploading the file
6. console now quits to prompt
